N2 - The first amplitude analysis of the decay Ds+→K-K+π+π0 is presented using the data samples, corresponding to an integrated luminosity of 6.32 fb-1, collected with the BESIII detector at e+e- center-of-mass energies between 4.178 and 4.226 GeV. More than 3000 events selected with a purity of 97.5% are used to perform the amplitude analysis, and nine components are found necessary to describe the data. Relative fractions and phases of the intermediate decays are determined. With the detection efficiency estimated by the results of the amplitude analysis, the branching fraction of Ds+→K-K+π+π0 decay is measured to be (5.42±0.10stat±0.17syst)%.
